To all whomft'zf may concern A Be it known that I, WILLIAM' ELLIOTT, a citizen of the United States` residing at Beatrice, in the county ofGage and State of Nebraska, have invented certain newand usefull Improvements in Bearings, of which the'follo'iving isa specification.'

VThisinvention relates to certain improvements .inbearings for grain drill and other rotary disks; and the objects and nature of the invention'ivill be readily understood by those skilled inthe art in the light ofthe following explanation of the accompanying Figure l, is a vertical sectional yiewthrough drawings illustrating` what I now believe to be the preferred yembodiment fromainong other formations, arrangements and con#V structions Within the spirit and scope' lof my invention. .k u l An object of the invention is to vprovide means and structures whereby the entrance of grit into thebearing will be `reduced to the minimum; whereby a Vlarge sup-ply of lubricant can be maintained in the bearing and Iin constant communication With the engaging surfaces; whereby Wear can be easily taken up; and Wherebythe interior ofthe bearing Will be readily accessible. z

.Afuither object of the inventionjis yto 'provide certain improvements in details of construction and in arrangements and forinations; whereby a simple, durable and highly efficient bearing will be provided for rotary disks, cutters and the like, employed in or in connect-ion with agricultural implements. Y e e The invention consists in certain 'novel and arrangements as more fully and pai# ticularly set forth and specified hereinafter.` Referring to the accompanying drawings:

strong plateA ory casting` 9, jojfv greater "diameter vthanthe ,opening in .theV disk.l This platebfits thel outer side face ofthe disk.v and is suitably .riveted or otlierwisefixed to the". disk', usually at points 10. ,At .its outer side, thisl plate yis f formed with, .an encircling flange 11 .having af ltrue,cylindrical inner bearing surface 12,- concentric with the axis of rotation offthe'diskand also concentric1 block.l The plate 9,',has afcentral opening.. concentricA With vthe.,axis ofrotation" to, `rfev ceive the neck 5 of the bearing block, and .isf` annularlyolfset around said central opening and toward the boot to provide circular bearing edge 14, snugly fitting and rotatory about the surface of the neck 5, and 'an annular recess or socket 15, between said edge 1 4, and the adjacent vertical side face of the bearing block. This socket or recess 15, is` tapered or vreduced from the outer side face of the plate toward the edge 14, for the purpose of contracting a packing ring 16, snugly around the neck 5, to fill the space between the edge 14, and the inner side face of the block.` IThis packing ring 16, is preferably composed of a comparatively large soft felt washer to snugly yfit Vand rotate on said neck and fill the space about the neck andbetween theedge 14, and jlthe side face of the block and effectively exclude grit from the interior 'of the journal box;

The surrounding beveled or tapered wall 'of the socket or recess 15, crowds and contracts the felt washer onto 'and snugly around the neck `5, as the washer is longitudinally compressed between the edge or annular lip 14, and theA side face of the block 4. The width of. the circumferential cylindrical bearing surface of the block 4, is slightly in excess of the width ofthe corresponding cylindrical bearing surface 12,of the journal box or disk hub, Aso that when the hub or bo-x is on the bearing block vwith the inner side surface of the block abutting against the corresponding surface 13, of the box, the `outer side or endof the block will project outwardly beyond the open outer end ofthe casing or box formed by annular flangell.. y

The removable section or member 17, of the .j ournal box or disk hub, provides an annular abutment or bearing surface 18, for the said outer vend of the ibearing block projected outwardly beyond the flange 11, of the Afixed member ofsa'id box or hub. This removable member 17, is in the formV of av'cylindri'cal cap lcomposed of a flat disk having a comparatively deep annular flange 19. The internal diameter ofthe flange 19, is greater `than the external diameter ofy the open-side box forinedb-y 'flange 11. The removable member is applied to the member fixed to the hub, to form the outerwall ofy then oil 'cavity 8, and to bring Ythe bearing surface 18, into engagement with the outer end of the bearing block, and so that the flange 19, circumferentially surrounds [the flange 11, and forms an oil chamber a, within `flange 19, and around flange 11, and be tween the plate 9, and the outer end or disk 17, of the cap or removable member.

`Anoil tight joint formed between the end edge offlangek 19, and the preferably ground annular surface 2O ofthe .plate 9. This 'oil V'tight joint can be .packed by a series of parallel superimposed separately removable thin flat rings or liners 21, arranged and compressed between the edge vof` flange 19, and said surface 20. These thin rings can be composed of paper, pulp material or any other suitable substance.

An oil hole can be provided Vthrough flange 19, and this hole is normally tightly closed by removable screw plug 22. Oil

passages or ducts 23, are also provided ex-` of oil from oil supply chamber a, over the outer edge of flange 11, and to the bearing surface 18, and also to the oil cavity 8, althrough said cavity 8, preferably constitutes anadditional original oil supply chamber.

The cap or removable section 17 19, is 1 removably and adjustably secured by several bolts 24, having their heads exposed and` accessible at the outer side of the removable cap and from thence extending through holes in said cap into tapped holes orsockets 25, extending `through the fixed meinber of the journal box. The flange 11, is provided with exterior enlargements 26, to provide sufficient thickness of metal or body to receive said 'tapped holes. The screws 24, are longitudinally adjustable in said sockets 25, to clamp the cap against the rings 21,

under the 'necessary pressure to maintain the desired oil tight joint, and also to maintain the desired comparatively close fit between the opposite ends or walls of the journal box and the side faces of the bearing block, and

also to maintain ythe desired snug grit-ex- 'il cluding-fit of the `felt washer 16, around the cylindrical neck 5, ofthe bearing block. By removing these bolts 24, the cap or removable section of the journal box is released and can be removed to expose the interior of Tt.'

the box, the oil chambers, the bearing block ioo andthe bolt 7.` The cap can be readily re moved Aand as lreadily applied and secured mrplace.

Byjmeans of the bolts 24, the cap can be f* readily adjusted to maintain the desired degreeof 'tightness against the bearing block.

'By'employingthe series of thin separately removable rings or washers 21, looseness due to wear of the bearing block and box can be F- quickly and easily taken up. Should the end surfaces of the bearing 4block and box wear to such an extent that looseness cannot be taken up by tightening the bolts 24, it is only necessary to remove one or more of the thin rings 21, until the desired tightness of the bearing can be secured by tightening bolts 24.

Material advantages are attained by providing the bearing with such extensive oil izo vriolioii containing capacity, and with the oil chamberl exteriorly of the bearing'surfaces and in'oil feeding communication therewith. f

By providing a j ournal' box with therelatively large removable section, the ou'terside of the `box can becompletely opened quickly and easily kbyuremoving fthe cap.; securing bolts andthe cap. The bearing, block can4 then be easilyY removed from the journal; box through lsaid open outer side,-after the boltisecuring the block-to ,the boot or'other support has been unscrewedfrom the boot.

' This .relatively large removable outer wall section of the box, also enables ine-[to quickly apply the block tov'thedisk journal ,boxfand secure the block :to thebolt.. The disk` can be' thusqremoved from th-e bearing block .or

Y the 'bearing' block from the disk, forany ing of a cup-like member fixed to the ropurpose without the necessity of cutting rivets or without requiring `other slow or dicult operations.

` :Itis-,evident that'variations, modifications and changes mightfberesorted to infthefmechanical expression .ofmy invention illus- `trated` Without departing from the spirit and scope of the invention andLhencewI-,do not wish to limit inyselfitolthe vexact disclosure hereof. f
